Exponential enhancement of sensitivity in Ramsey interferometry with optically thick ensemble of atoms
S. A. Moiseev, K. I. Gerasimov, M. M. Minnegaliev +2
Ramsey interferometry is a cornerstone technique for precise measurement of time and frequency in modern clocks. The Ramsey experiments are typically done in optically dilute sampl…

Optical quantum memory on macroscopic coherence
S. A. Moiseev, K. I. Gerasimov, M. M. Minnegaliev +1
We propose a quantum memory based on the pre-created long-lived macroscopic quantum coherence. It is shown that the proposed approach provides new physical properties and methods f…
